Specification of Letters Patent.

Patented Mai. 31, 1914.

Application filed June 25, 1913. Serial No. 775,750.

To all whom it may concern Be it known that we, Rrmonrn J. ALTGELT andCHARLES F. CAnLsoN, of South Bend, in the county of St. Joseph and Stateof Indiana, have invented certain new and useful Improvements in Flows;and we do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same,

This invention relates to plows and more particularly to the share andits relation to the other parts of the soil-engaging member or plowbottom,one object of the invention being to so construct a share havingno lateral flange or gunnel, that it shall be re inforced orstrengthened where the greatest strain occurs, and so that the scouringsurface of the share shall be sufliciently raised above the standard topresent a scouring surface which will be less concave than isaccomplished with a share as heretofore con structed with a lateralflange or gunnel at its rear end.

A further object is to so construct the share and connect it in itsproper relation with respect to the mold board, that the latter will beprevented from springing upwardly past the adjacent edge of the share.

With these and other objects in view the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a plan View of a plowembodying our improvements; Fig. 2 is a side elevation; Fig. 3 is asectional view, and Fig. 4 is a separate view of the share,

1 represents a standard or frog which may be conveniently madeapproximately V-shaped in cross section so as to form two wings ormembers 2, 3 to which the soil engaging members, constituting the plowbottom, are secured, said plow bottom comprising a mold board 4, a share5 and a landside 6.

The mold board at is secured to the wing 2 of the standard or frog 1,and its forward edge is beveled, as shown at 7. The share 5 is alsosecured to the wing 2 of the standard and its upper or rear edge isbeveled, as at 8, to overlie the beveled forward edge 7 of the moldboard and thus prevent the latter from springing upwardly.

The share 5 is constructed without a laterally and rearwardly projectingflange 0r gunnel such as heretofore commonly employed, and it maytherefore be termed a gunnelless share. Instead of employing a flange orgunnel, we thicken the forward part of the share, such thickened portionoverlying the lower end of the standard and extending approximatelytothe point of the share and has a shape substantially as indicated in thedrawing.

The thickened portion of the share may have a shape as indicated at 9 inthe drawing, and it may be provided with a shoulder 10. This thickenedportion 9 constitutes a patch which may be formed by upsetting, rollingor by welding. The thickened portion or patch 9 serves to reinforce orstrengthen the share where the greatest strain and wear are brought tobear, and it also serves to effect a raising of the scouring surface ofthe share above the standard so as to present a straighter or lessconcave scouring surface than is accomplished with a share having aflange or gunnel.

A bolt 11 is passed through the reinforced or thickened portion of theshare and through the wing 2 of the standard. This bolt serves the samepurpose as the gunnel bolt of a gunnel share, but the nut on this boltis more readily accessible than is the nut on a gunnel bolt, becausewith a gunnel share, especially on engine and heavy wheeled plows, it isdifficult to raise the plow high enough off the ground to get under thesame with a wrench.

The land-side 6 is secured to the wing 3 of the standard and projectsforwardly under the share so as to assist in supporting the latter, theforward end of said land-side projecting partially across the patch 9and terminating at the shoulder 10 on the latter.

The share is somewhat thicker than is the mold board, at the abuttingedges of these parts, and in order that those portions of the undersurfaces of the mold-board and land-side with which the edge of thelandside engages shall be continuous (avoiding the presence of anoffset) and thus afford a flush surface for the edge of the land-side,the share is depressed or ground off at its upper corner, thus formingin the under face of the share a recess or depression as the landside.

Having fully described our invention what we claim as new and desire tosecure by Letters-Patent, is

1. The combination with a plow standard and a mold board securedthereto, of a share provided with a patch at its forward portion andoverlying the standard, a bolt passing through the share, patch andstandard, and a landside having a tapering forward end underlyingthemajor portion of the if patch and terminating near the point of theshare.

2. The combination witha plow standard and a mold board secured thereto,of a share provided with a patch at its forward portion and overlyingthe standard, a bolt pass ing through the share, patch and standard, aseparate landside secured to the standard and having its forward portionunderlying the portion of the share having the patch, and an abutmentnear the forward portion of said patch for the forward end of thelandside.'

3, In a plow, the combination with a standard, a mold board securedthereto, a share secured to the standard and abutting against theforward edge of the mold-board,

a land-side secured to the standard and en-: gaging the under faces ofthe mold-board specification in the presence of two'subscribingwitnesses.
